The differences between PRO and BASIC masks?

The Cambridge Mask BASIC is a mask that we manufactured to complement our powerful PRO masks and to allow even more people to gain access to clean air.

Our BASIC mask is made with New Lab tested filtration technology and filters over 95% of pollution, gases, bacteria, and viruses with up to 90 hours of use.

The Cambridge Mask PRO is a fashionable pollution mask that comes in a range of patterns and sizes.

What makes PRO is different from BASIC is that the PRO mask is made by combining 3 unique layers; the outer printed layer, the three-ply particulate filter, and an activated carbon cloth which is tested by British Military Filtration Technology and filters almost 100% of pollution, gases, 99.6% of viruses and 99.7% of bacteria.

The PRO mask is also treated with silver to protect the wearer against bacteria and viruses which our BASIC mask doesn’t have. PRO masks have a longer lifespan compared to BASIC masks and can last up to 340 hours of use.
